Xi'an Zealchon Electronic Technology Co., Ltd. boasts over 15 years of civil engineering expertise. Located in Xi'an's high-tech hub, our 7,500 sqm facility is where precision meets infrastructure.
Partnering with Chang'an University and Xi'an University of Technology, we integrate cutting-edge research into every Asphalt Aging Vacuum Tank and PAV system we manufacture.
The "Xiya" trademark is synonymous with quality in Shaanxi Province, having earned national and ministerial awards for filling technological gaps in geotechnical and asphalt testing.
Information Gain Insight: Modern asphalt aging simulation isn't just about heat; it's about controlling oxidative kinetics. Our tanks utilize a "Dual-Phase Vacuum-Pressure" cycle that mimics 5-10 years of environmental stress in just 20 hours, a benchmark 15% more accurate than standard gravity-convection units.
Asphalt binders undergo complex chemical changes. Our vacuum tanks are engineered to comply with ASTM D6521 and AASHTO R28, providing a pressurized environment (2.10 MPa) at elevated temperatures to simulate long-term field oxidative aging.
Post-aging, the binder contains entrapped air. Our Vacuum Degassing Tank (VDT) removes these bubbles at 170°C, ensuring that subsequent Dynamic Shear Rheometer (DSR) tests are not compromised by air inclusions, providing a 99.8% pure sample.
Using advanced PID algorithmic controls, we maintain temperature stability within ±0.1°C. This eliminates "hot spots" that cause localized over-aging, ensuring the "Pricelist" value reflects the highest laboratory reliability.
We are currently developing neural networks that correlate real-time pressure fluctuations during the aging process with the final Bitumen Viscosity, allowing for predictive analytics before the test concludes.
As the industry moves toward eco-friendly binders, our 2025 roadmap includes specialized vacuum modules designed to handle the volatile organic compounds (VOCs) unique to bio-based asphalt without degrading tank seals.
Future iterations will feature IoT connectivity, enabling lab managers to monitor multiple aging cycles across global sites via a single dashboard, ensuring standardized quality control for multinational road contractors.
Large-scale projects like the "Belt and Road Initiative" require asphalt that withstands diverse climates. Our aging tanks provide the critical data needed to design asphalt mixes for the Gobi Desert or the humid tropics of Southeast Asia.
Reclaimed Asphalt Pavement (RAP) is the future. Our technology helps labs determine the exact "rejuvenator" dosage required by simulating how old binder will age further once it's back in the road loop.
Our Xi'an facility is a testament to the "Smart Manufacturing" era, combining artisanal engineering with robotic precision.
Equipped with high-precision CNC lathes, milling machines, and argon arc welders, we control the entire production vertical. This means "Wholesale Quotes" are direct-from-factory, removing middleman costs.
Every aging tank undergoes a 72-hour stress test at 3.0 MPa—well above the standard operating pressure—to ensure zero-leakage performance in the most demanding laboratory environments.
We provide full documentation for CE, ISO, and regional standards, ensuring that our machines pass local accreditation (like UKAS or AASHTO) upon arrival at your facility.
From voltage adaptations (110V/220V/380V) to software localized in multiple languages, we tailor our equipment to your regional needs without the "custom" price tag.
Our shipping protocols involve vacuum-sealed moisture protection and reinforced plywood crates, ensuring that precision sensors and pressure vessels arrive in calibration-ready condition.
By choosing Zealchon, procurement officers secure a 30-40% cost reduction compared to European alternatives, while maintaining identical or superior technical performance metrics.
